1 Claim, No Drawings WITH FATTY CHAIN The present invention-relates to a process for the preparation of polyhydroxyl non-ionic compounds, by polycondensation of glycidol on alpha diols with fatty chain, in alkaline catalysis, and to the products thus obtained.

This process of the present invention produces nonionic surfactants having the formula in which R designates a radical or a mixture of radicals, l5

namely aliphatic, cycloaliphatic and/or arylaliphatic with 7 to 21 carbon atoms, aliphatic chains which can be saturated or unsaturated, linear or branched, and. which can present oxygen and/or sulfur atoms, especially l to 6 and preferably 2 to 4, especially 2 or 3 ether, thioether and/or hydroxymethylene groups, n is any whole or decimalnumber greater than 1 and equal to or less than 10 and indicates the average degree of polymerization. In the process of this invention, there are condensed on an alpha diol having the formula: 25

R-CHOH-Cl-bOl-l (ll) where R has the above indicated meaning, in the presence of an alkaline catalyst or a mixture of alkaline catalysts, n molecules 'glycidol having the formula oHi- CH-CHzOH a M m As examples of radicals represented by R, the following are mentioned:

a. hexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl,

octadecyl, eicosyl and heneicosyl;

R'-S-Cl-l R'-s-c1-i,-ci-t,-o-cii,-, R-SCH -CH -CH -OCH R-CHOHCH -O-CH and R'-CHOH--CH -S-CH wherein R designates one of the radicals listed under R"O-CH2-, wherein R" represents 3,7,ll,l5-' amefllrlhsmde y wherein x y Pat. Nos. 2,089,569 and 2,131,142 of Ludwig Orthner:

and Claus Heuck.

However, the process indicated in these patents does not permit production of products that are sufficiently soluble from simple fatty alcohols or those which present an ether or thioether group. In fact, glycidol largely condenses on itself, forming polyglycerols that are immiscible with lipophilic chain compounds. This is not astonishing since glycidol is well known for its pronounced tendency to polymerize at ordinary temperature in the presence of basic catalysts such as methylamine, pyridine, sodium, potassium or sodium methylate, and this tendency to polymerization has been pointed out, particularly in the Journal of Polymer Science pt.A-l, 4(5), 1253-9 (1966) (English). See also Chemical Abstracts Vol.64, 1968 1.

On the other hand, it is very surprising to observe that by slow addition of glycidol to long chain alpha diols in the presence of alkaline catalysts at a temperature of l180C, preferably 140 to 160C, the reaction medium remains perfectly homogeneous and that.

hydrosolubility is reached for a relatively low mean degree of polymerization n.

The alpha diols thus appear to constitute a special group in the class of alcohols, whether it is a matter of simple alcohols or of alcohols comprising an ether and- /or a thioether group.

Polycondensation of glycidol is effected preferably in an inert atmosphere, e.g., nitrogen. A mixture of compounds is formed that are all of the general formula (I), but for which compounds the number of fixed glycidol molecules can be greater or less than the statistical mean value corresponding to the number of glycidol molecules used per molecul of mercaptan. As a result there is obtained a mixture of compounds with different values for n, in other words, having longer or shorter hydrophilic chains, the whole of the n values being statistically distributed about a mean value corresponding to the number of glycidol molecules per alpha diol molecule.

The alpha diols of formula (II) which are used as hydroxylation of non saturated derivatives; hydrolysis of substituted oxirane cycles; condensation of fatty chain mercaptans on glycidol; condensation of thioglycerol on alkyl halides or on fatty chain alpha olefins; and condensation of glycerol, glycerol isopropylidene and thioglycerol on substituted oxiranes or on alkyl tosylates or mesylates etc.

As basic catalysts there are used alkaline hydroxides or alcoholates, preferably of sodium or potassium, in proportions of 0.5 to 10 mole percent and preferably from 4w 8 mole percent with reference to the utilized diols.

The addition of glycidol to the reaction medium is effected slowly. It can last from several minutes to several hours (up to about 4 hours).

In the case of polyhydroxyl thioethers, the corresponding sulfoxides can be prepared according to a known process by addition of hydrogen peroxide, 30-35 percent, possibly in the presence of 0.5 to 10 percent by weight of a lower carboxylic acid, e. g. acetic acid, which allows utilization of less glycidol to obtain water solubility.

The invention likewise concerns products obtained according to the above described process. Most are more or less consistent pastes whose properties differ according to the nature of the R radical, of the intermediate ether, thioether or hydroxymethylene group when they are present, and upon the degree of polymerizatlOn n.

These are surfactants, and as the case may be, they are foaming agents, softeners, thickeners, peptizers or emulsifiers. Their water solubility is attained with a relatively low degree of polymerization n.

Thus, for example, products for which the lipophilic part is constituted by 1 1 to 14 carbon atoms are foaming agents which are remarkable in comparison to conventional non-ionic compounds, for substantially lower n values.

With longer hydrocarbon chains there are obtained thickening or emulsifier products. These emulsifiers are especially effective for polar oils and similar products.

The intrinsic nature of the hydrophilic groups of these non-ionic compounds permits, moreover, a very good p ib li y. ith p n ed. a ka i. solut o s which property permits their use in the textile industry, e.g., for mercerizing.

The present invention also relates to compositions intended to be used in cosmetics, especially shampoos, hair dyes, dispersions or emulsions, these compositions being characterized substantially in that they contain at least one product of formula (I).

The present invention also relates to dispersions and emulsions, and especially dispersions or oil-in-water emulsions of polar oils.

As examples of polar oils there can be mentioned vegetable oils such as peanut oil, castor oil, triglycerides of fatty acids such as octanoic and decanoic acids, fatty alcohols such as 2-octyl l-dodecanol, alkyl esters of fatty acids such as adipic, myristic, palmitic acid and solvents such as chlorobenzene.

The oil in water emulsions can include from 10 to 60 percent oil, 5 to 20 percent emulsifier and 30 to percent water.

Polyhydroxyl non-ionic compounds of the present invention can also be used to disperse alkaline earth s ap ..anisstzss al xssls i lanams ns ium ee .v

For each gram of soap to be dispersed, there is utilized 0.02-1 g, preferably. O.l0.2 g of the compounds of formula (1) in 100 ml solution to 400 ppm calcium chloride.

The test used to show this property is the one proposed by J. Alba Mendoza and C. Gomez Herrera at the 5th international detergents conference in Barcelona in 1968.

The table below shows, for certain compounds of formula (1) whose preparation appears in the examples which follow, the minimum quantity Q (in milligrams) that is necessary to disperse 50 mg sodium oleate in 50 ml water with hardness corresponding to a content of 400 ppm calcium chloride, under the test conditions described by Alba Mendoza.

The lauryl sulfate of sodium which appears .in the table was selected ascontrol because it represents the medium type of dispersant for alkaline earth soaps.

The'compositions, dispersions and emulsions can be. storedin aerosol cans under pressure and containing conventional aerosol propellants such as monochlorotrifluoromethane or dichlorodiflurormethane. They can also include various adjuvants, e.g., other surfactants.

The compatibility of most of the compounds of formula (I) with aqueous solutions of alkaline hydroxides, e.g., with 40 percent NaOH, is one of their particularly advantageous properties which permits their use in the textile industry, e.g., for mercerizing.

EXAMPLE 1 A mixture of compounds of formula (1) in which R indicates a mixture of alkyl radicals having 9 to 12 carbon atoms, n has a mean statistical value of 3.5, is pre pared by polycondensation of the glycidol on a mixture of C C alpha diols sold by Archer Daniels Midland Co., under the tradename ADOL 114.

To 54 g of the above mentioned diols in a mixture, with a hydroxyl number of 520, there are added 3.75 ml of a solution of sodium methylate in methanol to a concentration of 4.6 meq/g (millequivalents/gram). The mixture is heated to 155C, eliminating the methanol, and there are introduced, drop by drop, in the course of 70 minutes, 72 g of glycidol (0.87 equivalents epoxide).

The product thus obtained is a thick brown oil that is perfectly soluble in water and in 40 percent sodium hydroxide. The Kraft point for a 1 percent solution is below 10C. The turbidity point for a 0.5 percent solution is above 100C, both in demineralized water and in water that contains 10 percent NaCl.

To 43 g of the mixture of the mentioned diols with a hydroxyl number of 430, there is added 1 ml of solution of sodium methylate in methanol, to the concentration of 4.6 meq/g and, at 155C, drop by drop, in the course of 105 minutes, 38 g of glycidol.

The product thus obtained is water soluble and has a very slight opalescence.

. The Kraft point is below 0C.

The turbidity point for a 0.5 percent solution is above 100C in demineralized water as well as in water that contains 10 percent NaCl.

m EXAMPLE g which R-is the radical RS-Cl-l wherein R represents a mixture of straight chain and branched C12-C15 alkyl radicals of which about 14 percent are 2 methyl alkanols sold by the Shell Co. under the name Dobanol 25,- n representing a mean statistical value of 2.5, is prepared as follows.

In afirst stage, glycerol alkyl thioethers are prepared by reaction of the above mentioned alcohols with methane sulfochloride, with subsequent condensation of the thioglycerol in an alkaline medium.

205 g (1 mole) of Dobanol 25 are mixed with 101 g triethylamine in 250 ml benzene and in the course of minutes there are introduced, at 3040C, 1 14 g (1 mole) methane sulfochloride. After 1 hour of additional stirring the level of reaction is 97.5 percent.

After filtration of the triethylamine hydrochloride, there is added a stoichiometric quantity of the sodium derivative of the thioglycerol under nitrogen. The reaction mixture is brought to C with partial elimination of the benzene and with addition of 30 ml of methanol in the course of the reaction to avoid thickening o th east gmws The alkyl thioglycerol is then expanded with 100 ml water, decanted and then vacuum dried to a temperature of 100C.

To 65 g (0.2 mole) of the product thus obtained, there are added 2 ml of methanol solution of sodium methylate to 4.6 meq/g. The mixture is heated to C and there is then added, dropwise in the course of 90 minutes, 0.5 mole glycidol.

The thioether prepared in this way can be oxidized to sulfoxide with stoichiometric quantities of hydrogen peroxide in the presence of 0.5 percent acetic acid, yielding a product that iswater soluble.

The Kraft point at 1 percent is 19C. The turbidity point of the product at 0.5 percent is 80C in demineralized water and 68C in water that contains 10 percent NaCl.

The foam heights measured with the Ross-Miles apparatus at 35C in hard water are respectively 10.5 cm, 16.5 cm and 18 cm for concentrations of 0.05 percent, 0.2 percent and 0.5 percent, respectively.

"EXKMFLE Z i A mixture of compounds substantially identical with those of Example 3, with the difference that n represents a mean statistical value of 3 is also prepared. This slight increase in the value of n results in an increase in the range of solubility of the polyhydroxyl sulfoxide, i.e., a lowering of the Kraft point to 8C and an elevation of the turbidity point above 100C in demineralized water, and to 85C in water that contains 10 percent NaCl.

The foam heights are not much changed, however. They are respectively 10.5 cm, 15.5 cm and 18.5 cm.

After a night at 25C the reaction is total. The triethylamine hydrochloride that has formed is filtered off and the sodium derivative of the thioglycerol is added. The benzene is partly eliminated and 50 ml methanol are added. After 2% to 3 hours of stirring at 40-45C the level of reaction is 95 percent.
